` nikon? To all whom ity may concern.'

'Be it known that I, Vvnimazu C. BosWELL, a citizen of the UnitedStates, residing at Rossville, in the county of Nalker and State ofGeorgia, have invented certain new and useful Improvements in Hinges:and .l do declare the followin l to be a` full, clear, and exactdescription o the invention, such as will 'enable others skilled in theart to which it `appertains to make and use the same.

T ns invention relates to improvements in spring hinges and especiallyto hinges for use on screen and other doors which are removed andreplaced at intervals.

The object of the invention is to provide a simply constructed, strongand efficient hinge, one member of Vwhich remains in osition on the doorcasing at all times an the other member is carried by the Adoor anddesigned to remain thereon, said members being provided respectivelywith cooperating means for detachably connectin them whereby the doormay he readily etached from the casing .Without removing the screwsorother fastening device, thereby avoiding the marringl. of the casinresulting from the insertion and removal o the screws and also saving`time andlabor required for unscrewing and screwing of the members.

Vith the foregoing and other objects in view, the invention consists ofcertain novel v features of cfmstruction, combination and arrangement ofparts, as Will be more fully described and particularly `pointed out in.the ap )ended claims.

In t e acconipanyin' drawings, Figure las a front elevation oiv aportion of a. door and casing with this improved hinge applied and withthe door in closed position; Fig. 2 is a. t.ransverse section taken onthe line 22 of Fig. llookin downward in the direction of the arrow;i`ig. 3 is a vertical section taken on line 3 3 of Fig.' 1,2 Fig. 4

is a front elevation of the hinfre leaf adapted Aof the hinge. 1 and 2.are shown preferably composed of sheet metal having their ends bent atri 'ht angles to form ears or knuckles 3, 4, 5 an 6 which are pivotedtogether by means of rivets 7 and 8.

the leaf 2 is slit transversely a short distance and the tongue soformed is rolled leaf 1 is provided with a plurality of Vaper'- tures aslil to receive the fastenin screws by means of which it is attached to tie door.`

This leaf 1 is also provided in its knuckle or ear 5 with a recess orsocket 1e to receive one end 15 of a s ring 15 having a coil 16preferably forme intermcdiately of its ends and with its other end bent.in the same direction the end 15 and extended through the.l

socket 9 formed at the inner edge of the leaf 2, and the terminal ofsaid end is 'pref- Y erably bent at right angles and is adapted toengage the leaf 2 asshown for exerting the necessary tension thereon.

the door With its hinge edge arranged in t alinement with the outer edgeof the `door as shown to permit the opening of said door. A keeper plate17 is attached to the door casing by screws or other suitable fasteningdevices in posit-ion to be engaged b the leaf 2 as will noW bedescribed. This plate 17 is provided at its front edge with a tongue 18rolled backward to form a hooklike device adapted to engage the rolledback tongue which forms the s'ocket 9 of the leaf 2. At the rear edge ofthe plate 17 is formed a knuckle 19 dlsposed opposite thev socket member18 in position to fit in the recess formed between the knuckles 10 and11 of the leaf 2.

When the parts are assembledfass shown clearly in Fig. 1, the leaf 2extending' over and completely covering the plate 17 there 10o byprevents the working out of the fastening screws of said plate 17. Thepintle 12 is passed through the registering knuckles 10, 11 and 19 ofthe members 2 and 17 respectively and is preferably provided at one L95end with a finger piece 12' formed by bending said end at an angle tothe body portion thereof to provide for the ready insertion and removalof said pintle when it is desired to connect or disconnect the leaf 2and 110 The leaf l is attached to the rear edge of assembled theshoulders formed on the leaf 2 by cutting out the tongue from which isformed the open knuckle 9 are engaged by the ed s of the hook-likedevice 18 of the plate. 7 which holds the door against sagin o Igromtheforegoing description taken in connection with the accompanyingdrawings, the construction and operatlon of the invention will bereadily understood without -requirin a more extended explanation.

Various c anges'inthe form, proportion and the ,minor detailsofconstruction may be resorted to without departing from the principleor sacricing any of the advantages of the invention, `as defined in theappended claims.

I claim as my invention l.. The combination with' two pivotaly connectedhinge leaves, one of which has a laterally extending device on the ed ethereof, of a keeper plate having a hoo like device for'engagement withsaid laterally, extending device, co erating knuckles carriedby saldplate and lleaf, respectively, and a removablel pintle for connectmthem.

2. The combination with Vtwo pivotally connected hinge leaves, one ofwhich `has a lateral. projection arranged thereon, of a keeper-'platehaving a rearwardly curved tongue for engagement with said lateralproiection, coperating knuckles carried by sai plate and leaf,respectively, and a remova le pintlefor connecting them.

3. The combination with two ivotally connected hinge leaves, one ofwhich has a thekeeper plate 17. When the parts are f laterally extendinglongitudinally disposed projection arranged adjacent its hinged edge onone free thereof and provided at its opposite: edge withl verticalh7spaced knuckles having a recess arrange between them, of a keeper platehaving a knuckle at one ed e disposed to fit in the recess between ie'knuckles of said leaf an'd aline with said knuckles, a rearwardly curvedtongue arranged vopposite the knuckle on sai plate to engage thelongitudinally extendin lateral projection of said leaf, and a pint efor insertion in said knuckles.

4. The combination with two pivotally connected hinge' leaves, one ofwhich has vertically lspaced laterally exten-.ring knuckles,

transversely extending slits formed thereinto provide a tongue,saidtongue being rolled backwardly to form a longitudinally extend'-` ingsocket with shoulders at its top and bottom, said leaf being provided atitsmfposito edge with vertically spaced knuckles tra.' Ain a recessarten ed between them, a keeper plate having aA nuckle at one edgedisposed to fit in the recessl between the knuckles, a rearwardly curvedltongue arranged on the other edge of said keeper plate to engage thelongitudinally extending socket forming device of said leaf, and apintle for-insertion in saidV knuckles. i

In Vtestimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
